API Route Structure

The best way to structure API routes is to apply consistent patterns like file-level JSDoc, step-by-step implementation comments, organized imports, and helper extraction to keep route files clean and maintainable.

Document API routes by adding a comprehensive file-level JSDoc header to each route.ts file that outlines the route's purpose and usage, supplemented by in-route step comments for routing logic and error handling.

Organize imports by grouping them logically at the top of the route file, and extract common or reusable logic into separate helper files under lib/helpers/ to improve readability and modularity.

Yes, this API route structure pattern includes built-in guidance for error handling and performance considerations, ensuring developers implement safe and efficient routing logic step by step.

You should extract logic from an API route into a helper file when the code becomes reusable across multiple routes, promoting cleaner route files and better overall project maintainability.
